Decalogue of good practices for the use and maintenance of LED Curing Units

Currently, several resin-based restorative biomaterials harden through a photopolymerization reaction, for which a polymerization unit (UP) is necessary. The objective of this manuscript is to generate a guide based on current scientific evidence for the correct use of UPs. A search was made for articles published from 2002 to January 2022 through PubMed and Google Scholar. The information was organized into 10 relevant topics in the form of a decalogue: wavelength, light intensity, tip diameter, curing time, curing mode, curing distance, use of barriers, battery and charging, cleaning and disinfection, and regular checks. Health professionals must know and remember the importance of a proper use and maintenance of PUs, since this can influence the clinical performance of the biomaterial.
